A12, 1929 waan l `LOUIS wERNrCKE, or WEST BEND, WISCONSIN AIR MOTOR Application ined January 9, 192e. serial .No.,ziafisa This invention relates to improvements in air motors of the type covered by my Patent No. 1,628,867 patented May 17, 1927, the prin,- cipal objects of the present invention being to improve the construction of the air motor and to provide starting and stopping means for the same and also to provide governor means for controlling the speed of the motor.

This invention also consists incertain other` features of constructionand in the combination and arrangement of the several parts,

inder carrying wheel and its associated parts.v Figure 4 is a section on llne 4-4 of Fig# ure 3.

Figure 5 is a view of the parts which are connected with the pull rod `for operating the bell crank for moving the rod in the shaft and the cable which operates the bell crank which controls the openingand .closing movement of the main wheel.

i in these drawings, 1 indicates'the housing which is rotatably mounted in the tower 2 and 3 indicates the main shaft which passes through the housing and is journaled therein and to which is connected, at one end thereof, the main wind wheel A. A sleeve 4 is journaled in the rear part of the housing and surrounds a portion of the shaft kon which it ro` tates and a wheel B has its spokes 5 connected with the outer end of said sleeve so that the wheel will rotate with the sleeve. The other set of spokes of this wheel B are connected to a hollow shaft 6 which is rotatably mounted on the rear part of theshaft 3. The

wheelC has one set of its spokes 7 connected to a hub 8 which is fastened to the rear end of the shaft and the other set of spokes is connected to a hub 8l which is rotatably mounted on the hollow shaft 6.

A bevel gear 9 is keyed to the shaft 3v andV is'arranged in the housing 1 and this gear meshes with a gear 10 connected with the upper vend of the vertically arranged driven shaft 11 journaled inthe tower and this gear meshes with abevelgear 12varranged in the housing and is keyed to `theinner end of the .sleeve 4 so that the sleeve is rotated from the n V10 is also Mmnged inthe housing. Gear 10- wheel A and in an opposite direction tothe n direction of rotation of the shaft 3. Thus wheel' B is rotated in an anti-clockwise` direction, wheel C rotating inal clockwise direction v or in the same direction as wheel A..

Each of the wheels Band C carries a plu-'i rality of radially arranged-cylinders 13, each cylinder being fastened to a shaft .'14 which passes thro-ugh the center of the cylinder and has itsrends journaled in the outer ring 15 and the inner vring 16 of thewheel. y The ini' l ner end of each shaft 14 hasl fastened thereto ka bevel pinion 17 which meshes with a large gear 18, the gear 18 of wheel B being rotat-v ably arranged on the shaft 3 andthat of the wheel C being rotatably arranged on the hol-` low sha-ft 6. Each gear 18 has fastened thereto a drum forming flange 19.

' A standard 2O has its central part formed shaftj3, this standard being yarranged ad'- jacent ythe gear 18 of wheel B vand a similar `standard-21 is arranged adjacent the gear 18 of wheel C, this standard 21 being rigidly A arranged on the hollow shaft 6. Each standard ycarries anezipansible band 22 of split ring type with its ends connectedtogether by .a coil spring 23 which normally holdsfthe band contracted. Each standard also carwith -a hub "which is rigidly mounted on the ries a pair of clutch members 24, one of which is pivoted toeach lendof the standard and these clutch members 2,4.are wideenough to v extend over the drum 19 and over the band 22. .Coil springs 25 are adjustably connected f with the standard and with extensions 24. of

Athe members 24 by the bolts 26, these springs normally holding the clutch members in enl gagement with the drum 19 so that the gear 18 volving at a certain speed and thus act to re,

lease the gear 18 from the standard and thus check the movement of each wheel, these parts acting as governor means for preventing each wheel from revolving too fast.

'A slide 28 is arranged on each standard and this slide is connected by the links 29 with the ends of the band 22 so that when the slide is moved outwardly, the band is expanded against the action of its spring and will thus v movethe clutch members 24 outwardly out of engagement with the drum 19. The slide associated with a standard of wheel B is adustably connected bythe bolt and its nuts 31 with one arm fof aV bell crank 32 carried by the standard, and a link'33 connects the other end of the bell crank with a collar 34 slidably mounted on the shaft 3 over a slot 35 in said shaft and said collar is fastened by a pin 36 to a rod 37 which passes through a hole formed in .the center ofv the "shaft Y 3. The slide which is associated with the standard of wheel C is connected by a link 38 with a collar 39 slidably mounted on the shaft and fastened bya pin to the rod 37. A. grooved collar 40 is pinned to the rodand is slidably arranged on the shaft 3 within the housing l, this :collar being shifted back and forth by the Inove-Y ment of a bell crank 41 arranged within the housing and pivoted to a hanger carried by said housing. A link 42 connects the bell crank 41 with a cross piece 43 in the housing, the center part vof the cross piece being connected to a pull rod 44 which passes through a centrally arranged holel in the shaft 11, with its lower end connected to a lever 45 by a pin 45 which engages a groove in a ring-Shaped partof the lever so that the pin ,can rotate with the shaft. The lever is pivoted to a bracket 46 on the tower. The pin 45 is located in a slot'47 in said shaft 11. A member Y 48depends from the lever so that the lever can be operated from the lower part ofthe tower.

ring arranged in the groove of a collar 56 which is slidably mounted on a hub part 57 of the wheel A. Links 58 connect the collar 56 with the bell cranks 59 carried by the wheel A, these bell cranks being connected byl the links 60 with the crank shafts 61 of the wheel, these crank shafts carrying the van'es 62 of the wheel. A weighted lever 63 is pivoted to the standard 53 and is connected with the lower arm of the bell crank 52 by the link 64.A A f Y A housing surrounds the gear 18and its clutch parts of each wheel, each housing revolving with the wheel,by being connected with the inner ring of each wheel, the central portion of the housing of wheel'B rotating on the shaft while that of the housing of wheel C revolves on the khollow shaft, the outer end of A vFrom'the foregoing it will ybe' seen-that this housing being connected with the hub 8.v Y

when the wind wheel is rotating, the shaft 3 which is connected with wheelV C will cause said wheel C to rotate in the samedirection standard 2O of wheel B is keyed to the shaft and will rotate with said shaft, but the standard of wheel C is keyed to the hollow shaft f 6 which rotates with wheel B so that said standard ofwheel C will-rotatein the same direction as wheel B, but in an opposite direction from wheel C, while the standard of wheel B will, rotate in an opposite direction from that of wheel B. As the clutch members are in engagement with the drums of the gears 18, said gears must revolve with the standards, and as the gear 18 of wheel B is revolving in an opposite direction from wheel B, the shafts 14 and their cylinders 13 will be rotated throughthe engagement of the lpinions 17 with the gear 18.' The gear 18 of wheel C is also connected with its standard by the clutch means so that this gear, meshing with the pinions of the cylinders, will rotate said cylinders, but these cylinders of wheel C will be rotating in an opposite direction from the cylinders of wheel B.A Y

The effect of wind strikingthe rotating cylinders is an increase of pressure with a decrease of wind velocity, on the side on which the wind strikes, and a decrease of pressure with an increase of velocity of the oppositev side'. By the application of the Magnus law, the area of decreased pressure and increased velocity will,` at certain cylinder speed, extend approximately three-fourths of the way around the cylinders. It has been found thatthis effect is attained when the cylinders are rotated at about four times the wind velocity, and the developed pressure will' then beabout fifteen times'greater than ordinarily.

Thus the wheels B andl C will act with wheel A in driving the shaft 11. flf tliespeedof rotation exceeds a point for which ,the governors are set, the weighted par-ts will swing outwardly under centrifugal action, thus lift- Vingthe clutch members off the drums l9of V the gears 18 and thus the `movement of the cylinders will be checked and the whole ap-` paratus slowed up until the speed lessens sufficiently to permit the springs to return the clutch parts against the drums, which will cause the drums to be rotated again.

`When the device is to be stopped, the pull rod 44 is pulled downwardly by means of the lever 45 and its connections, so that the cross piece 43 will be lowered, exerting a pull upon the links 42 and 49, which will Iswing the bell crank lever 52 downwardly and 1 Vthe weiohted lever 63 upwardly. The link 54 l expand the bands 22 so as to push the clutch aoygnembers off the drums of the gears 18 and thus disconnect the gears from the standards and thus the cylinders will cease to operate.

A spring 41, connected with the bell crank 41 and adjustably connected with the top of Y the housing l, is provided for moving .the

parts to a position to relieve the expansion members when the pull rod 44 is released, thus preventing the members 30, 31 and 38 from locking the clutch parts in operative i As will be understood, the wind wheel simply acts as a starter for the cyclinder carrying wheels, though I provide means whereby said wind wheel will help the cylinder carryingl wheels to operate the power transmitting shaft and the load when the device is in operation, though said cylinder carrying wheels will be operated by the wind even though the wind wheel is in inoperative position.
